Why did I not get my senior deduction

[AnnetteB6]

The additional senior deduction enacted due to the One Big Beautiful Bill Act (OBBBA) is not reported as part of the standard deduction on your tax return.  Instead, you will see it included automatically based on your age and filing status on Form 1040 line 13b.  

Amounts shown on line 13b can be traced back to Schedule 1-A line 38 where the total Enhanced Deduction for Seniors is calculated.

the senior deduction is phased out when line 3 of Schedule 1-A is $175,000 or more for a single person,
